Reflective Memory (RFM) networks are designed to provide the tightly timed performance necessary for a variety of distributed simulation and industrial control applications. By using RFM systems, designers are able to eliminate most communication latency and realize drastic improvements in resource utilization over traditional LAN technologies. The benefit of a low-software, high-speed, hardware-driven network like RFM is extremely low data latency, both overall and between individual network nodes. This low-latency performance important when building real-time systems such as simulators, PLC controller systems or test stands. This white paper presents a discussion of RFM as a complete functional system as well as suggested best practices that will enable the user to obtain the highest value from RFM products.
